I better order my FTTC as soon as they go LIVE otherwise if the 288 lines is full then I cannot order FTTC.

It won't have 288 lines of capacity straight off. It'll have perhaps 96, 2 full length line cards, and those won't fill up that quickly as the area has >14Mb DSL and cable.

True. My area had mixed ADSL2+ and Cable (Virgin Media) but maybe BT try this one the biggest cabinet (hold 400+) here: http://postimg.org/image/ytdjfnwyr/

You were doing so well then you lost the plot a bit.

As I'm sure you're aware given that you took it from this page that's a non-issue as that's a b4rn cabinet which means that every subscriber connected has their own pair of optical switch ports.

An FTTC cabinet that size would hold considerably more than 400 connections.

There will be a % use rule that BT are using

Current Line capacity of cabinet (for the number of houses + business lines) * (factor if cable) * (factor remaining on ADSLx) * {the 'special commercial number'} = size of cabinet to install day 1 with initial number of FTTC connection points for 'sale'

Then its just an anticipated fill rate depending on marketing sales and demographics.

if they then use a bit of monte carlo analysis, they can then work out the best cabinet size, fiber size and card layout for the new cabinets.

I'm pretty sure it's nowhere near that complicated, PCPs with Virgin Media cable passing 300-350 premises getting Huawei 288s doesn't really seem appropriate if it's that exact given Virgin Media's take up of 40%+.

There also doesn't appear to be any kind of calculation for how many line cards and tie pairs to put in to begin with it seems to be a standard build.

A cabinet near here is on its 2nd closure for new capacity having filled the first tranche of ports in a week.

The cabinet I'm connected to, scheduled to go live in November, will be even worse than that one, having as it has a campaign to drive interest, passing a considerable number of premises, having no cable, poor mobile signal so tethering is problematic, and being home to ADSL that doesn't reach 'basic' 2Mb levels.

I can't see it taking long for that one to chow through 96 ports and suspect 288 won't really last given the cab is >450 premises now and will be over 560 when building is complete.

We have 115 cabs installed in our area, and every single one of them I've seen, which is the majority is a 128 line ECI cab.

If the 288 line cabs are not much more it does make you wonder why they haven't just used them, then it's just a case of adding more hardware internally when/if needed, rather than another cabinet when capacity runs out.

Are you sure they are all 128 line cabinets. The ECI cabinet shells are the same size

Same here, Mine is go LIVE in November. Wish us both best of luck with superfast FTTC.

No, I'm just going by the info here. So this cabinet can cope with more than 128 lines then?
